Abstract

The invention relates to a high-efficiency aerator based on a pneumatic swirl forced mixing technique. The aerator comprises an aerator casing, an air inlet pipe, a mixing zone and swirlers. The swirlers include a primary swirler and a secondary swirler. The mixing zone and the swirlers are arranged in the aerator casing. The aerator casing arranged vertically is of a hollow horn-shaped structurewith an open top and an open bottom. The aerator casing comprises a large horn end and a small horn end which are connected vertically. A water inlet is arranged at the bottom of the small horn end, and a water outlet is arranged at the top of the large horn end. The high-efficiency aerator based on the pneumatic swirl forced mixing technique has the advantages that the aerator is free of fine aeration holes, clogging of the aeration holes by suspended substances in water is avoided, the gas-liquid mixing effect is improved, and the sewage treatment efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, aerator and swirl mixing, in particular to a high-efficiency aerator based on pneumatic swirl forced mixing technology and its application. Background technique [0002] In the treatment of industrial wastewater and domestic wastewater, there is a very important equipment: aerator. This kind of water treatment equipment is widely used in various forms. The function of the aerator is to blow air into the water to increase the oxygen concentration in the water. At the same time, a large number of air bubbles formed by strong air pressure also play a role in uniform water quality, which is beneficial to the subsequent biochemical process and reduces the impact of uneven water quality on microorganisms. effect. [0003] Most of the equipment currently used in the aeration process of sewage treatment uses membrane or hose aeration devices. Although these two methods are simple, there are v...
